Shell脚本：循环读取含50个数字的文本文件两行内容并赋值变量
Here's a clear, practical breakdown of how to format content using Markdown, with examples for each requirement you listed:
Headings
Use number signs (#) to define headings. The count of # determines the heading hierarchy:
# Level 1 Heading→ # Level 1 Heading## Level 2 Heading→ ## Level 2 Heading### Level 3 Heading→ ### Level 3 Heading
You can go up to 6 levels of headings total.
List Items
Begin each list entry with a dash (-). For nested lists, indent the dashes by 4 spaces or a tab:
- Main list item 1
- Nested list item 1a
- Nested list item 1b
- Main list item 2
Emphasized Text
Wrap text with asterisks (*) to add italicized emphasis:*This text will appear emphasized* → This text will appear emphasized
Code or Commands
Enclose inline code/commands in single backticks (`). For multi-line code blocks, use triple backticks (```) (you can optionally add a language tag for syntax highlighting):
- Inline example:
git status - Multi-line example:
#!/bin/bash echo "Hello, World!"
Quoted Text
Use greater than signs (>) to create blockquotes. For longer quotes spanning multiple lines, add > to each line or just the first line of each paragraph:
This is a sample quoted text. It can wrap across multiple lines, and you'll see it styled as a distinct blockquote.
Here's a second paragraph in the same quote block.
Links
Structure links with square brackets for the visible display text, followed by parentheses containing the target URL:[Check out this resource](https://example.com) → Check out this resource
Images
Start with an exclamation mark (!), then square brackets for alt text (descriptive text for screen readers or if the image fails to load), followed by parentheses with the image URL: →
